Frankly, It might rely to the fact that tentacles in the tentacle porn genre can do one thing which real men cannot do,

and that is to satisfy women by occupying 2 or 3 orifices at the same time.

question: why just in japan though? or do you know any other place where tentacle porn would have been quite a common thing to cross over? - regarding that japan ain't the only place surrounded by oceans and seas

Because when it comes to eccentric tastes, Japan is quite open about it.

Well, back in the day, while I was still living in the Philippines (1984 - 1999), porn newspapers where accessible to the public and on the streets. A little boy can purchase porn newspapers /cigarettes/alcohol/gin by simply telling the vendor, "my dad told me to buy this for him."

I never seen any tentacle fantasies but there are comic strips about this lady who has a mole on her private and she gets really horny/free when it's stimulated. Or a daily fiction article of a lady who has 3 boobs.

But, now, I don't think those porn newspapers are freely circulated for the public to read. Maybe because of newly-elected officials in the office or consecutive after consecutive news about ladies/young girls getting rape by their fathers or other family members.

yes, that may be true, but still doesn't explain the psychological ongoing in someone's head that would lead him to have sexual thoughts about tentacles and raping girls. why would they have such an urge, the urge that made them envision the perfect monster that would achieve their perverse desires with no bigger trouble, to think of something that would be bigger than their own penis?

Same goes to pedophilia, bestiality and fetishism, Psychologically-speaking, Things like this often come at random, some men often find it weird that they are much more pleasurable to touch,feel or smell a woman's feet than sex itself(foot fetish), while some men prefer girls who are underage girls than women(pedophilia), Same goes to men who like tentacle porn, In fact, eccentricities when it comes to sex has a a very wide range.

paedophilia is still bound to the human body, so is foot fetishism...zoophilia *gasp*

meh, i bet it has something to do with the japanese's small sexual male organ *cough cough* >.>

My cousin has a load of hentais that involves tentacle sex...
I tried watching his supposed favorite where the girl is sort of in a bondage situation and there
were so many red-ish fat tentacles just penetrating her holes... And it's all slimey...and tentacle-ish (-___-)
I find it awfully creepy and disturbing.
But I guess if it can be put into something....the end justifies the means? Ha ha.
The cause of tentacle porn...well, maybe because it's something that men or women can't possibly do in real life sex. Isn't that what porn is about?
